Help!!! Off depo possible pregnancy!!

Okay so I was on the depo for two years and just got off of it the beginning of the month. My husband and I had unprotected sex on the 8th and I took the day after pill. I had my period from 14-18 but it was so light I didn't have a heavy day or anything. Well we made the same mistake again on the 18 at midnight the last day of my period. I had white discharge the day after. Do you think I'll end up pregnant?! I haven't had a period in two years so I'm so scared.
